Application filed December 30, 1915. Serial N 0. 69,380.

To all to 700m it may concern Be it known that I, DELASKA A. KENDALL, a citizen of the United States, and a resident of San Diego, in the county of San Diego and State of California, have invented a certain new and useful Improvement in Horseshoe-Calks, of which the following is a specification.

One of the principal objects of my invention is to provide an improved hollow calk which may be welded in position on a horseshoe, and which is adapted to receive tarred rope or other suitable material, for preventing an animal on which the shoe is worn, from slipping and sliding, the rope or other material being removable from the calk whereby the latter may be used on icy or sleety streets to cut into the ice and thus provide a firm foothold for the animal.

A further object of the invention is to provide an improved calk of the class described which will be extremely simple, durable, efficient in operation, and inexpensive to manufacture.

With these and other objects in view which will become apparent as the description proceeds, the invention resides in the construction, combination, and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawing in which like characters of reference indicate like parts throughout the several fig ures, of which Figure 1' represents a plan view of a horseshoe equipped with calks constructed according to my invention. view in section taken vertically and longitudinally on the plane indicated by the line 22 of Fig. 1. Fig. 3 represents a view in section taken vertically and transversely on the plane indicated by the line 33 of Fig. 1. Fig. 4 represents a view in perspective of one of the calks removed.

In carrying out my invention, I provide a calk including a split or continuous flattened ring or loop, formed of suitable metal. The rings may be made at the forge by hand, or may be manufactured by machincry, and may be made either split or continuous as desired. In equipping a shoe with the calks, for instance, in the arrangement shown in Fig. 1, the portions of the shoe to which the calks are to be attached Fig. 2 represents a.

are heated until they are red hot and the prongs. 'aredrive'n or pressed into the hot metal of the shoe and the calks welded in place.

The calks may be provided at intervals on their inner surfaces, if desired, with V- shaped channels or recesses indicated at 7 in the drawing, extending from the lower edges of the calks upwardly and decreasing in depth toward the upper edges of the calks. The inner lower corners or edges of the calks will thus be roughened, and will more readily cut into snow or ice. The calks may, however, if desired, be manufactured without the channels or recesses.

The calks are adapted to be filled with lengths of tarred rope or other suitable material indicated at 8, this filling being packed into the calks serving the purpose of adhering to the surface of the street or pavement so as to provide a steady foothold and to prevent the animals foot from slipping. The filling material, it will be found, will collect sand and gravel which will add to its wearing qualities and which will also augment its adherence to the street surface. The calk filler is intended to be removed when the streets are extraordinarilv slippery, due to the presence of sleet, ice, or snow thereon. so that the lower edges of the calks may thus more readily cut and bite into the surface of the roadway. When the calks wear ofi", it is not necessary to throw the old shoe away, new calks being replaceable upon the old shoe in place of the wornout calks. The old calks can be refilled at any time with tarred rope or other material, without removing the shoes from the animals feet.

Although I have described the preferred embodiment of my invention, I may desire to make such changes in the construction, combination, and arrangement of parts thereof, as do not depart from the spirit of the invention and the scope of the appended claims.

I claim 1. A horseshoe calk comprisinga flattened ring, a spur carried by the ring adapted to be pressed into the body of a horse shoe, said ring having its inner face provided with spaced recesses extending from the lower edge of the ring upwardly providing a cut- -0opies of this patent may be obtained for [ting edge for the lower surface of the ring, and'ea fi'lling material reinovably disposed Within the ring. Y I I c 2. A horseshoe calk comprising a hollow ring, a spur carried by the ringadapted to be driven into the body of the horseshoe,

said ring having its inner surface provided 1 ring "having its inner surface provided at spaced lnterva ls with recesses defining a cutting edge for the lower portion of the vcalks, and -a filling detachably arranged within the ring.

4. A horseshoe calk comprising a hollow ring having a spur adapted to be driven into the body of a shoe whereby the ring mav be welded onto the shoe, said ring having its walls provided with vertically exr-itending recesses to form a cutting edge for the lower portion of the calk.
